Tovv all whom it may concern? Be it known that I, HERBERT S. MFILLs, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inVending-Machines, of which the following is a specification. The objectof my invention is to provide a novel construction of vending machine inthe class employing a magazine for holding a stacked supply of thearticle to be delivered from the base of the stack ea'ch. time themachine is worked upon being rendered operativc by inserting into it acoin of proper denomination.

I have devised my improvement more especially for vending sanitarydrinking cups; and it is hereinafter described in that par tioularconnegtion and so illustrated in the accompanying drawings, inwhichigure 1 is a view of the-machine in front elevation with a portionof the front casing- Wall'broken away to disclose parts of the operatingmechanism,- Fig. 2 is a section on line 2, Fig. 1, showing the underside of the casin top, which contains an opening and forms the base ofthe magazine provided with supports at intervals about the openii'ig forsustaining the stack of folded cups from the bottom v of which thedelivery is produced; Fig. 3 is a perspective view of one of the foldedsanitary drinking cups with a portion broken away to show a detail ofconstruction; Fig. 4 is a partly broken section on line 4, Fig; 1,condition the coin-controlled mechanism for actuating thedelivery-mechanism of the n1achino, and Fig. 5 is a similar View showingthe coin-controlled mechanism under actuation; Fig. 6 is a section online (3 4; Fig. 7 is an enlarged section on line 1, Fig. 1, showing thedelivery-mechanism; Fig. 8 is a section on line 8, Fig. 7, and Fig. 9 isa plan View regarded at the line 9, Fig. 8.

The drinking-cup 10 (Fig. 3) to be vended by my improved machine,ture-proof (paraflined) paper out of a suitable blank flaring from itstransverse center toward its ends and folded upon itself at the center,with flaps 11 on the edges of one section folded over and cemented tothe edge-portions of the'other section. Thus, in the normal condition ofthe cup, the sections are flatwise together as represented.

The case 12 is shown of rectangular shape Specification of LettersPatent. Application filed an as, 1911.

with a removable with a suitable kc the top .16'of the case is formed an17 surrounded by a 'flarige 18 and of the gencup 10, with lugs 19projccting'inwardly, one from each edge, to form an open seat for-astack of the cups lowermost cup in the stack may be readily withdrawn.The top 16 ailords'the base of a magazine, which may be formed of a cagecomposed of upright rods 20 rising at suitable intervals from the flange18 and connected at their upper ends, to tie them stably together, by aband 22 fastened by nuts 23 on the rods and a cylindrical hood 24,preferably of glass to render it transparent for displaying the contentsof the magazine, and provided with a perma .nent metal cover 25,envelope the cage and is fastened at a metal flange 26 about its loweredge to the top 16.

In the top near one corner of the case is a which extends downside ofthe adjacent a coin-chute 28; The lower, discharge end of the chute28registers with a recess 29 in the segmental head 30 of a lever 31fulcrumed near its lower end, at 32, to the side-wall of the case,adjacent to a stop33 for limiting the returnwardly on the innerside-wall of the case movement of the lever, the lower end of whichcarries a finger 34 connected by a spiral spring 35 with a stud 36 onsaid wall. To this same wall is ulcrumed between its ends a lever 37carrying on the inner face of its outer-end portion an obliquelyextending lug 38 against which bears the lower, headed end ,of avertical push-rod 39 working through, the top of-the case in a bearing40 and provided on its outer end with a knob 41.

It will be noted that by depressing the operating push-rod, the lever 27is forced against the head '30 with the latter upon a dead center anddoes not, therefore turn the head; whereas by introducing a coin 42 r(Fig. 1) through the chute to lodge in the front wall 14 equipped-operated lock 13 and I ,containing a lower-dclivery-opening 15.

8n the bottom of the case is fastened, at a foot 52,-aI verticallyslotted standard 53 inwhich is reciprocabl provided on its outer' acewith a stud 55' which projects through the relatively short slot in theback'of vthe standard and is connected with a stud56 on the standardnear its lower end by a coiled retracting-spring 57 An angular arm -58secured at the slot in the'standard to the inner face of thereci'procating bar 54, carries on its u per end a suction-cup 59,preferably of so t-rubber,

and has a stnd 60 projecting from near its lower end to extend acrossand under the adjacent end-of the arm 51. The position of the cup 59' isin line with the center of the'magazine-opening 1 With a stack 61 of theflat drinking-cups 10 in themagazine, and preferably having a' weight 62resting upon it.for its resistance to the actionof the pneumatic cup 59,the

machine is ,operated as followsz'Upon in-,

In rising, the arm 51 encounters the horizontal section ofthe arm 58which carries thecup 59 and raises the'bar 54 to impinge the cupcentrally a ainst the lowermost drinking-cup 10 m t e stack. Theoperation is so timed that just-after the suctioncup'is pressed againstthe bottom' of the stack, the dog 48 clears and trips the arm confined abar-54' 49 when, also, the pawl 46 has cleared the rack 45, permlttingthe-spring 47, upon the operators releasing the ush-rod, to retract thelever 37 to its norma position (Fig. 4).

Upon the release of the arm 49 from the dog 48, the spring 57 suddenlyand forcibly retracts the bar 54 and cup latter in descending to pul 59causing the away from the stack and off the seating lugs 19 through theI magazine base-opening 17 the lowermost cup On the lever 7 near itsinner end is pivot 10 ally secu'reda spring-pressed do 48, whichprojects beyon perform the tripping purpose upon the ad y thesuction-action thereon of the on 59. The folded drinking-cup thus pullsout drops on a curved chute-plate 63 exthe'opening 15 in its front wal,beyond which it forms a delivery-tray 64 (Fi 7) for the lodgment of thevended drinl in cu where --it is accessible for removzfi. W cm thechute-plate extends over the suctlon-cup and its attendant mechanism, itis cut out, as shown in 'Fi 7, to provide an opening 65 through whic tolivery-mechanism to work.

-What I claim as new and desire to secure by Letters Patent is 1. In avending-machine, the combination of a case provided with a top-openingadapted to seat aboutrit a stack of articles to be vei1ded,adelivery-opening and a chute permit the deleading thereto, a magazinefor the stack,-
